HEAT EXCHANGE SYSTEM AND REFRIGERANT CYCLE INCLUDING HEAT EXCHANGE SYSTEM

A dual expansion valve for a refrigerant cycle of a vehicle that includes a first inlet and a first outlet, a first flow restriction mechanism including a movable first valve element, by which a firstrefrigerant stream flowing through a first passage from the first inlet to the first out let can be controlled, a second inlet and a second outlet, a second flow restriction mechanism including a movable second valve element, by which a second refrigerant stream flowing through a second passage from the second inlet to the second outlet can be controlled, a control member for jointly moving the first valve member and the second valve member, a sensing element for sensing a temperature, and a valve driving member that is configured to drive the control member according to the sensed temperature. The dual expansion valve can be applied to the heat exchange system. 一种用于车辆的制冷剂循环的双膨胀阀，包括：第一入口和第一出口；第一流动限制机构，包括可移动的第一阀元件，通过该第一阀元件可以控制从第一入口流过第一通道到第一出口的第一制冷剂流；第二入口和第二出口；第二流动限制机构，包括可移动的第二阀元件，通过该第二阀元件可以控制从第二入口流过第二通道到第二出口的第二制冷剂
